Dextroamphetamine causes my orgasms to feel like seizures.

This may be the weirdest thing i've experienced on drugs (so far). when taking dextroamphetamine, when I orgasm, it feels like a seizure, and i get a little blackout. i usually get the shivers for a while along with the post orgasmic "after glow".<br><br><br>&#x200B;<br><br>I can't explain it, but it's like a normal orgasm, but a million times more intense. anyone else felt something like this? i know the drug increases dopamine and serotonin levels in the brain, but is there some other mechanism i'm not aware of that would explain why i get an almost seizure-like feeling when i orgasm?<br><br>&#x200B;<br><br>&#x200B;
